He provides control loop optimization services and training to industrial companies worldwide and has more than 20 years of experience in process control, including seven years in power plants.

By Jim Ford, PhD. Just over a decade ago, an article titled, "Advanced Control Strategies Move into the Field" (Control, October 2008), highlighted three evolving trends in the process control world ...

Finding and fixing process control loop problems that PID tuning cannot correct. ... But for level control purposes, linearity of the slave flow loop is less important than repeatability. By reducing ...

Mike: Nearly every analog instrument uses the 4-20 mA loop. Field transmitters, positioners, and variable frequency drives ...

Only through proper troubleshooting and then solving the underlying problems can control loop performance be improved. Process design certainly plays a role in control loop performance, but ...

According to process control experts, a detailed and specific set of control valve requirements is more than necessary when it comes to good control loop performance. Control valve selection plays a ...

Industrial control systems can be categorized in two types: open-loop and closed-loop systems. The open-loop control system is a continuous control system that provides no feedback from its output.

Not so fast. The next complaint you’re going to get from product test is excessively long ramp-up and ramp-down times for the fan. Also, it may have ceased to oscillate, but never reaches the desired ...

In my estimation, this combination of human-in-the-loop automation can automate anywhere from 40%-100% of the process done by traditional BPOs, depending on the complexity, while helping ensure ...
